  Chapter 1: Overview of Thermodynamics

  
  

  Thermodynamics is the branch of physics and physical chemistry that deals with energy, heat, work, and their transformations in physical and chemical processes. It provides fundamental laws governing the behavior of macroscopic systems and is essential in fields like engineering, chemistry, biology, and environmental science.

  Chapter 2: First principle of thermodynamics

  
  

  This course introduces the First Law of Thermodynamics, the fundamental principle governing energy conservation in physical and chemical systems. You will learn how energy is transferred as heat (Q) and work (W), and how these interactions affect a system’s internal energy (U). Applications range from engines and refrigerators to biological processes and chemical reactions.

  Chapter 3: Applications of the first principle of thermodynamics to Thermochemistry

  
  

  This course explores how the First Law of Thermodynamics (ΔU = Q + W) governs energy changes in chemical reactions. You will learn to quantify heat transfer (Q), work (W), and internal energy (ΔU) in reactions, with applications to calorimetry, bond energies, and reaction spontaneity. Key topics include enthalpy (H), Hess’s Law, and standard reaction heats, bridging theory with lab techniques like bomb calorimetry.

  Chapter 4: The second principle of thermodynamics

  
  

  
  

  This course explores the Second Law of Thermodynamics, which governs the direction of natural processes and introduces the concept of entropy (S)—a measure of disorder or energy dispersal. You will learn why some processes are spontaneous (e.g., ice melting) while others are not (e.g., heat flowing from cold to hot). Key topics include Carnot cycles, Gibbs free energy (G), and thermodynamic efficiency, with applications to engines, refrigerators, and biological systems.

  Chapter 5: Free energy and enthalpy - Criteria for the evolution of a system

  
  

  In thermodynamics, the criteria for system evolution provide fundamental tools to predict:

  1. Whether a process can occur spontaneously (without external intervention).

  2. The direction and extent of a physical or chemical change.

  3. Equilibrium conditions (where the system stops evolving).

  These criteria are rooted in free energy (G) and enthalpy (H), bridging the First and Second Laws of Thermodynamics.
